While I believe that some of the QC complaints I've read lately have been somewhat overblown (or even non-existent), others are definitely cause for concern. Especially when creating something special like an MTO, Meermin needs to ensure that the product that leaves their factory is top quality. As a relatively new company it runs the risk of being seen as a low cost, and low quality, provider. That would be a shame considering the quality of goods they usually create.
I've ordered four pairs of shoes from them and all of them arrived in great condition and still receive compliments when I wear them. However, I think that the run of MTOs that have been placed lately has overtaxed the company as when I inquired about getting a standard pair of shoes in a different color I was told that they were rather swamped at the moment. Maybe this is leading to a lack of QC overall. This is why, while I start to drool at the thought of getting in on one of the museum MTOs, I haven't taken the plunge. I think I'll wait till the rush is over then see about either joining in on a group order or starting my own.
